All releases of CDRX

Release Notes: There is a bugfix to comply with POSIX regular expressions. This appears to be relevant to Red Hat 8.0 systems. Also of note is that the tarball now decompresses everything into a cdrx-(version) directory, rather than dumping everything into the current directory.

Release Notes: With this release, the entire program has been rewritten in Perl "strict" mode. The "intro" screen now only appears during fresh installs (or whenever it doesn't find the settings file). CDRX now supports multiple SCSI buses, and checks to ensure /var/db actually exists, doing a mkdir if necessary. Full status output during blanks, burns, etc. now goes to standard output.
